Hi Sir, This Is Abhishek From Kanpur, Actually My Father

Hi Sir,
This is Abhishek from Kanpur, Actually my father had a heart attack on 27 Dec and after that he had gone through angiography on 29 Dec.
According to Angiography report, He had 3 arteries blocked and as per doctor's recommendation, He had done angioplasty for one blockage and for next 2 blockages planned for 15 Jan.
I am not sure whether I am on right track of treatment or not. Some people suggested me for by pass surgery and some for angioplasty . So looking for your expert suggestion and recommendation for the same.
